Move deleted user accounts files from banyan to amanda.

On banyan check the total size of all the deleted files:
```
sudo du -shc /home/*/deleted
```
Login to amanda and become root.
If there is not enough space to copy the old accounts to /deleted on amanda, we need to make space:
```
find /deleted -mtime +400w -delete
```
This will remove any file older than 400 weeks (about 8 years).
Start with 400 weeks and reduce by 50 weeks until there is enough space available.
Do the same for /host/localhost/ada7/home.
Note: we cannot check the disk space abailable on /host/localhost/ada7 because it is shared with Amanda backups, so we must do the same delete as for /deleted. (We can check the size of everything that is not home of the disk ada7.)
Delete ghost directories that have been left empty after removing older files:
```
find /deleted -depth -type d -empty -delete
```
Do the same for /host/localhost/ada7/home.
Go to the disk ada7:
```
cd /host/localhost/ada7
```
Copy the deleted files from banyan:
```
ssh on@banyan sudo -A tar cf - /home/\*/deleted | tar xfBp -
```
On a non-graphic environment, you may use -S instead of -A but be aware that the password will show in clear on the screen.
Go to the deleted directoriy on the system disk:
```
cd /deleted
```
Repeat the step 6.
Login on banyan and become root.
Go to the home directory:
```
cd /home
```
Remove the deleted account files:
```
rm -rf */deleted/*
```

The following steps are needed to upgrade FreeBSD sources using subversion.

Install subversion from the ports.
Run it once to create the proper environment:
```
sudo svn checkout http://svn.FreeBSD.org/base/releng/9.2 /usr/src
```
This will fail but create /root/.subversion
Edit the file /root/.subversion/servers, in the section [global] add the following lines:
```
http-proxy-host = 192.41.170.23
http-proxy-port = 3128
```
You can now update FreeBSD source, above steps will not be necessary anymore. The command is:
```
sudo svn checkout http://svn.FreeBSD.org/base/releng/9.2 /usr/src
```
